Bay Thermostat
During cold weather, locate the bay thermostat next to the
Plumbing Manifold. This thermostat controls the heat exchanger for the
holding tank bay heat. Adjust the thermostat between 40 to 50° F. To help pre-
vent freezing of the water system.
NOTE:
Turn the Aqua-Hot ON when heating the bay.
Coolant Tank
Monthly:
Check the Aqua-Hot 50/50 solution of water and antifreeze to ensure
its proper level. Visually inspect the coolant level in the expansion tank
when Aqua-Hot is at operating temperature. Adding solution to the
expansion tank when the unit is cold will result in a solution overflow
when the Aqua-Hot attains normal operating temperature. The expansion
tank is located behind the fuel door.
CAUTION:
Use only a non-toxic propylene glycol based boiler
antifreeze. For more information, contact Vehicle Systems at
1-800-685-4298.
Annually:
Have the Aqua-Hot tuned up yearly. A tune up consists of a fuel noz-
zle and fuel filter replacement, as well as a thorough cleaning of the com-
bustion chamber. This simple tune up will keep the Aqua-Hot running
smoothly throughout the year, as well as allow service personnel to inspect
for additional wear of other components. Signs that the Aqua-Hot may
need servicing are continuous white exhaust smoke or poor ignition start
up. When in operation, the Aqua-Hot should have a smooth, high-
pitched whine. Loud growls or other abnormal noise indicate service or repair is required.
CAUTION:
Before cleaning or servicing disconnect all power supplies.
